Abstract.Thermal expansion of zirconium was investigated in the temperature ranges 350^1220K and from 1035^1830K in two dilatometers. The reasons for the change in the size of the sample in the phase transformation region are analysed. The obtained results are coprocessed with the
of silica sand’s abrupt thermal expansion and unstable crystal phases, dimensional accuracy of castings produced in these materials is compromised. Zircon, chromite, and various mullite ceramic aggregates are being chosen to replace silica in high accuracy castings because of their low thermal expansion and dimensional stability.
Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide.These oxides are commonly called "zirconia" (Zr O 2) and "yttria" (Y 2 O 3), hence the name.
